Stability of uniform fluidization revisited

Sergeev, Y.A.; Swailes, D.C.; Petrie, C.J.S. - In: Physica A: Statistical Mechanics and its Applications 335 (2004) 1, pp. 9-34

The marginal stability of uniform gas-fluidized beds is analyzed making use of ‘macroscopic’ conservation equations … adopted approach, the stability of uniform fluidization can be explained without reference to the hypothetical solid …-like state of the particulate phase. The criterion of stability is derived in the form of the critical particle volume fraction …

Pinning control of scale-free dynamical networks

Wang, Xiao Fan; Chen, Guanrong - In: Physica A: Statistical Mechanics and its Applications 310 (2002) 3, pp. 521-531

Recently, it has been demonstrated that many large complex networks display a scale-free feature, that is, their connectivity distributions have the power-law form. In the present work, control of a scale-free dynamical network by applying local feedback injections to a fraction of network nodes...

Stochastic persistence and stationary distribution in a Holling–Tanner type prey–predator model

Mandal, Partha Sarathi; Banerjee, Malay - In: Physica A: Statistical Mechanics and its Applications 391 (2012) 4, pp. 1216-1233

In this paper, we study a stochastic predator–prey model with Beddington–DeAngelis type functional response and logistic growth for predators. The deterministic model is already well-studied and we recall some important results here. We construct the stochastic model from the deterministic...

The stabilizing effect of noise on the dynamics of a Boolean network

Goodrich, Christopher S.; Matache, Mihaela T. - In: Physica A: Statistical Mechanics and its Applications 379 (2007) 1, pp. 334-356

In this paper, we explore both numerically and analytically the robustness of a synchronous Boolean network governed by rule 126 of cellular automata. In particular, we explore whether or not the introduction of noise into the system has any discernable effect on the evolution of the system....

Dynamics of a cooperation–competition model for the WWW market

Wang, Yuanshi; Wu, Hong - In: Physica A: Statistical Mechanics and its Applications 339 (2004) 3, pp. 609-620

We present a model to describe the dynamics of web sites on the WWW market. The model accounts for cooperation and competition at the same time. Our goal is to establish strategies for web sites to win on the WWW market. Unlike the known competition systems, the model shows unexpected...

Moving average rules as a source of market instability

Chiarella, Carl; He, Xue-Zhong; Hommes, Cars - In: Physica A: Statistical Mechanics and its Applications 370 (2006) 1, pp. 12-17

Despite the pervasiveness of the efficient markets paradigm in the academic finance literature, the use of various moving average (MA) trading rules remains popular with financial market practitioners. This paper proposes a stochastic dynamic financial market model in which demand for traded...

Some issues on the stability of trading based on technical analysis

Alvarez-Ramirez, Jose; Fernandez-Anaya, Guillermo; … - In: Physica A: Statistical Mechanics and its Applications 337 (2004) 3, pp. 609-624

Some stability effects of technical trading on financial/commodity markets are analyzed in this paper. Technical … equation, whose (local) stability is determined by means of root-locus techniques. It is proven that the larger the time …-delay horizon, the larger the stability margin. This means that short-run technical trading is more likely to induce market …
